Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-940

Enforces verification of the source of a communication channel by requiring identification and authentication of services first.

addresses: CWE-20

Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.

addresses: CWE-20

Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.

addresses: CWE-940

Requires explicit verification of the source and integrity of the channel used for authentication and other security functions.

addresses: CWE-940

Provides the means to verify the source of name-resolution responses instead of relying on unauthenticated channels.

addresses: CWE-940

Requires explicit verification of the communication source, blocking session hijacking via spoofed or alternate channels.

addresses: CWE-20

Directly implements checks on information inputs to reject invalid data before processing.

addresses: CWE-20

Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
